What type of insecticides are generally considered safer for the environment?

Biorational insecticides are generally considered safer for the environment due to their targeted nature and lower toxicity to non-target organisms. These insecticides are derived from natural materials, such as plants or certain microorganisms, which tend to have less impact on beneficial insects, wildlife, and humans compared to conventional insecticides. They often work by disrupting specific biological processes in pests without affecting other organisms, making them a more environmentally friendly option.

In contrast, conventional insecticides are often broader in their application and can be more harmful to the ecosystem because they may affect a wide range of species, including beneficial insects. Systemic insecticides, while effective at controlling pests through absorption by the plant, can also pose risks to non-target species if they enter the food chain. Contact insecticides tend to be applied directly and can kill any insect that comes into contact with them, which can lead to broader ecological impacts.

Thus, biorational insecticides stand out as a more sustainable choice for pest management, aligning with integrated pest management practices that prioritize environmental health.
